摘要
系统地研究了钙硫化、趋近饱和温度、SO2 入口浓度、喷嘴雾化风量、分层喷浆及加压消化等因素对烟气脱硫效果的影响 ,结果表明 :增大钙硫比 ,降低ΔT ,采用分层喷水及加压消化等有利于提高脱硫率 ;在Ca S比为 2 .5的情况下 ,加压消化喷浆脱硫的脱硫效率可达 6 5
Effects various factors on the effectiveness of flue gas desulfurization were researched. Such factors include: approach saturation temperature, SO2 inlet concentration, atomizing airflow rate of nozzles, injected layered lime slurry and pressurized slaked sorbent, etc. The results of the study indicate that the adoption of an enhanced Ca/S ratio, a reduced ΔT, a layered water spray and pressurized slaked sorbent are conducive to increase the desulfurization efficiency. Under the condition of a Ca/S ratio of 2.5 the desulfurization efficiency with the use of pressurized slaked sorbent can exceed 65%.
